WING-POST SOCKET.

Specification of Letters Patent.

rat-meu nar. 11,191.9.

To all whom. t may concern Be it known that l, HENRY Knncnnnu, a citizen of the United States, reslding at Buffalo, in the. county'of Erie and State ot N ew York, have invented certain new and useful Improvements in `Wing-lost Sockets, of which the following is a speciiication.

My invention relates in general toy aeroplane strut sockets and more particularly to that class `of sockets used for attaching the wing post of the aeroplane to the wing beams thereof. rljhe wing post socket of vmy invention is of practically universal construction by reason oi its interchange-ability. Moreover, my invention provides as an integral `part of the wing post socket. a means whereby may be attached and securedthe necessary guy or stay wires which are used tobrace the aeroplane structure.

The nat-ure andrelation of the parts to be joined, e.,-wing post and wing beam is such that heretofore it has been found necessary to provide a special socket or fastening foreach particular position or station along the aeroplane wing beam duel to the fact that the angularity ot' the center line intersections of the beams and posts is dii"- ferent for diilerent points along the structure. Init-s varied embodiments my invention is designed to overcome the atorementioned objections;

In obtaining the features which contribute to the adaptability ol' my socket I utilize a pressed metal fitting in conjunction with a U-bolt ofspecial design, 'the combination being of such nature that the metal body or main portion of the socket serves to receive and retain the engaging wing post. extremity while the U-bolt serves to secure. the body ot the socket to the wing beam ot the aeroplane, structure and simultaneously to provide snitable loops or bulged portions to which may be adjustably attached` the wire pulls or stays. These details are set forth in the dra wings of which:

Figure 1 is a side view of my aeroplane wing post socket;

Ysa

Fig. 2 is a view of the socket in section Fig. 3 is a iront view ol' the socket in an.

assembly of wing beam, wing post, socket and stay wires.

ln Fig. 1 the socket 10 is shown attached to the wing beam 11 by means of the U-bolt 12. The upper part of the socket 10 is drilled to receive the bolt 13 which pene-v trates the end ot' the projecting` wing post 1l and thereby secures it. The U-bolt. 12 is ot special looped form, the loops 11). thereof serving to accomodate the clips, tastenings or terminals 15, Fig. El. carried b v the ends.. of the turnbuckles 16 which serve to render taut the stay wires. 'lhe main bod),v 1() ol' the socket has two walls or sides rising mutually parallel t'rom the flat base 1T which larries at its extremities the two projectingcars 1S. 'lhese latter mentioned cars irc drilled so that the)v may be bent upwardly at an angle to receive and retain the terminating loops ot' the dritt wire extremities 19, Fig. 3. In the event that only one oi" these cars is utilized, which is usually the case, the ienlaining one is simply cut away from the, main body otl the socket. This disposition contributes largely to thc universality' oi' the socket. l

rl`he sides'or walls 10 ot' the socket are provided with slots 20, Fig. Z which serve to permit the passage ot the loops 12, Fig. i in assembling the socket and U-bolt. lt is to be noticed that the position ot this slot. is such that the extremities thereof arc not in vertical alinement but are slightly otiset one from the other, Fig. 2. "lhe extremities ot this slot t'orm retaining interstiees for the U-bolt 12 and the bolt. 1?). 'lhe straightened threaded portions ot' the U-bolt penetrate 90 the. wing beam 11 through holes drilled therein and are held by means of nuts 22 which are screwed ther-min. lnterposed betwecn'the nuts 22 and the wing beam 11 is a flat plate or distended washer 224i which serves as a proper bearing surface for the nuts 22 and protects the surface ol' the wing beam therefrom.

The extremity oi the wing p ost 1l is. shaped radially about the center oi' the bolt 13 and bears simultaneously upon the innermost side ol' the socket 1T and against the flattened center portion 2l otl the U-bolt l2, Fig. 2. The flattened portion 21 of the U- bolt and the tial base ot the socket combine.

vto form an angular recess which serves t0 permit of a limited amount of radial oscillation of the wing post 1-t about the center of the bolt 13 or laterally of the socket, at the same time securely fastening the wing post to the wing beam. ln lateral adjustment the ears 16 should be bent. r1`hus thel utility of the socket is not limited to a particular location involving a specific angle of wing post and wing beam but may be used in a number of places with equal facility, since the dihedral angle. the stagger and the sweepback of the wings may be freely varied without materially all'ecting it. The only change which the above variation in angles involves isa slight bending of the upstauding ears 16 and the ears 1.7 and 1S. This slight change'is readily accomplished since 1 construct my socket of sheet metal which permits of bending to the desired forms.

In disclosing the features of my invention I have used more or less detailed forms but 1l do not consider my invention limited thereby as various constriu-tional changes may later be iliade without iuany way departing fro|u`the spirit or principle of my invention. y

'hat is claimedis:

1. A strut socket for air craft comprising a body haring upstamlingears arranged to receive a strut end between them aml hav- `ingtherein alincd slots lying in a plane at an angle to said body, securing means for the socket passlng transversely through said slots at one end thereof and securing means for the strut end'passing transversely of said slots toward the other end thereof.

2. .A strut socket for an' craft comprising `11pstanding ears spaced apart and having 4an elongated slot together `with a U-bolt passing through .said slot to accommodate the bight therein andarranged to secure said socket to the craft.

3. `Al strut socket for air craft comprising upstanding ears spaced apart and havmg an elongated slot together with a U-bolt passing through said slot to acconnnodate the bight therein and arranged to secure said socket to the craft7 the biglit-ot' said U-bolt having lobes formed at its opposite corners for the attachment of lift wires.

1+. A strut socket f/oLai-rcraft comprising a main body and Securing means therefor together forming an angular recess arranged to receive the end of a strut, together with means to attach the strut to the body of the socket.

5. A socket comprising a socket member, and a U-bolt having its bight centrally indented and bearing by its indented portion upon said socket member and having a width greater thanY said socket member whereby the lobes formed von the extremities of the, bights b v the indentation thereof may be used for the attachment of lift wires.4

(i. A strut socket for air craft comprising a main body having ears bent up to receive a strut end between them and provided with angular slots` a securing U-bolt having its bight indented and otl a width such that when passing through said slot said indented portion bears transversely upon the body ot' said socket between Asaid ears andthe lobes thereof- :afoject beyond the ears of said socket respectively whereby an angular recess is formed between the body ofsaid socket and said U-bolt. to longitudinally po` `its engagement therewith limit its angular displacenient.

' In testimony whereof I atlix my signature.
